This example does not use template function from template function and it is also dependent on return type. My problem is that I call template<T>bar from template<Arg>foo and want foo to call bar<Specific> when I pass Specific to foo 😭

Hi I've got template function that I directly call somewhere: template<class First, class ...Rest> void foo(First && first, Rest && ...other) const { bar(first); bar(other...); } It invokes these: template<class Arg> void bar(Arg && single) const { std::cout << single << ' '; } void bar(Specific && specific) const { std::cout << "SPECIFIC"; } template<class ...Args> void bar(Args && ...args) const { (bar(std::forward<Args>(args)), ...); } I thought that it gonna work because C++ chooses the most specific overloading, but, as I see, it doesn't if I call it from another templated function, so bar(Specific) never be called. I know, that if I directly call bar then bar(Specific) will be used if I pass Specific type, anyway, from in templated function it is not. Help please 😔

I've already tried this, but this functions are methods, so I cannot use template<>. I'll try again with separate struct to use template<>

how to access other class variable and read it's real-time value? variable value changed, but from other class Im still getting old value

how about - if constexpr (!std::is_same_v<First, Specific>) { bar(first); } else { void (Class::* fn)(Specific &&) const = &Class::bar; (this->*fn)(first); }

Probably you passed by value instead of a reference somewhere

As long as this "Config config;" isnt pointer it's runnable, If changed to pointer (changed . to -> ofc), app just crashed

I have two classes, one Config and the other "XYZ" class. In XYZ class I have "Config config;" (in private). Then Im reading Config variable in XYZ class function (in loop, printing default value no matter what).

nah, I dont use const

If I have declared Config object as pointer in XYZ public and then in main this: Conf config; Building building; building.config = &config; its working good. What is this?

Is it necessary to have this to "read" real-time value of other class variable?

so what is the other way to "read other class variable value in real-time"

Lol you've got to allocate memory to a pointer

Hi

Hi I've got template function that I directly call somewhere: template<class First, class ...Rest> void foo(First && first, Rest && ...other) const { bar(first); bar(other...); } It invokes these: template<class Arg> void bar(Arg && single) const { std::cout << single << ' '; } void bar(Specific && specific) const { std::cout << "SPECIFIC"; } template<class ...Args> void bar(Args && ...args) const { (bar(std::forward<Args>(args)), ...); } I thought that it gonna work because C++ chooses the most specific overloading, but, as I see, it doesn't if I call it from another templated function, so bar(Specific) never be called.

what is this code does?

Write a program to group the words according to their lengths from a given string S using a Hash Table of size k with separate chaining. Assume that only alphabets are present in the string S and maximum size of the string is 500. The words of the string are grouped using the following formula. Index_No = (length_of_word ∗ length_of_word)%k where % is the modulo operation and k is the size of hash table. If the string contains multiple occurrences of a word w, then it should not be added again in a group. Only the first occurrence of w is added to the group. Note: Hash table is implemented as an array in which each entry contains a head pointer to a linked list which contains the words of the same group. Words generating same Index_No belong to the same linked list (refer sample output for explanation). Duplicate words are not allowed in the list. Each node of the linked list is of the following type. struct node{ char *word; // word to be store struct node * next; //pointer to the next node }; Input Format: • First line of the input contains an integer ‘k’, the size of the hash table. • Second line of the input contains a string/sentence of words. Output Format: • Each line of the output should print the index number and words in it, separated by a colon(:). • The words inside a group are separated by minus sign(-). • If no words are present in the group then print ‘null’ in place of words. Sample Input 1: 3 Write a program to create a hash table. Sample Output 1: 0:create 1:Write-a-program-to-hash-table 2:null Sample Input 2: 5 This program is a program to create a hash table Sample Output 2: 0:table 1:This-a-create-hash 2:null 3:null 4:program-is-to

Can anybody help me with this?

Can anybody help me with this?

Sorry I have tried but not able to find the logic can anybody help?

what have you tried?

please i need help i have a c project to write a c program that is able of converting numbers to word like 100 and the output is one hundred any hints please

pthread_join function changes the state of the pthread_t struct it gets as argument?

It can't change the pthread_t it gets as argument because it doesn't have a reference to it. The argument is passed by value, it means it only receives a copy of it.

You can first split the value into array of digits, and fill additional (3-size%3) elements with zeroes. So for 1234 it will be { 4, 3, 2, 1, 0, 0 } Then you can reverse iterate over each three elements and decide what you want to output. You will also need a function that converts a digit to a string depending on the position in the triplet. Also a function that will return correct string for the given index of a triplet ("thousand", "million") So in my case I would do two iterations, for first process 0, 0, 1 and output "one thousand " The second iteration would be 2, 3, 4 and something like "two hundred thirty four "

Hi guys, how to connect to Google services like contacts with C? There is some library or some code to do it?

Google Contacts is deprecated and superceded by People. Google offers a REST API that you can use with basically any programming language that supports network calls. To connect to it you probably want to use OAuth2.0 to authenticate the user and use the provided token for subsequent requests https://developers.google.com/people

scanf("%d ",&a); Why does adding a space after %d makes the program wait for more input?

(Find the Smallest) Write a c program that finds the smallest of several integers. Assume that the first value read specifies the number of values remaining

that sounds like some assigment / exam question

Just doing some practise....

It's kinda ultra easy and could be found in Google, you're wasting time

okay.... and why have you send the message then if you are practicing?
